Title: Integrated circuit
Inventor: LOEFFLER STEFFEN
IPC: H01L21/822
Filed: 1999-06-09
Abstract: PROBLEM TO BE SOLVED: To reduce the noise effect and timing error of an integrated circuit off-chip driver for fast operation by allowing the resistance between a circuit and power supply buses to be basically equal while substantially higher than the resistance of the power supply bus. SOLUTION: Each of off-chip drivers 102 is connected to a bus 106 through an upper side terminal 104 and to a bus 108 through a lower side terminal 104. Resistors R3 comprised by each of the upper side terminals are all basically equal, being substantially higher than a resistor R2 of the bus 106. Resistors R4 comprised by each of the lower side terminals are all basically equal, being substantially higher than a resistor R5 of the bus 108. The buses 108 and 106 are connected to voltage lines of voltage levels DDG and VSSQ, by terminals 126 and 128. Thus, the resistors R3 and R4 inserted in series in the off-chip driver 102 and the buses 106 and 108 reduce noise effect, etc.

Title: Control system for residence of bus order
Inventor: TACHIKA SHINJI
IPC: G06F13/20
Filed: 1985-07-23
Abstract: PURPOSE:To prevent the reduction of the processing performance of a central processing unit by holding an answer signal which, without returning it, represents that a receiving is impossible for some time when a controller is in processing. CONSTITUTION:A WL order from a n order analysis circuit 5 is inputted to a busy detector 5, and when the WL order that is not processed is accumulated at a WL bus data part 5-1, it is detected that a state is busy. When a busy state is detected, a timer 8 is started up. And only as far as a controller 1 is not completed a process by a prescribed time is passed, the answer signal which represents that the receiving is impossible is returned to a central processing unit CP2 through an SP bus 3. As a result, while the timer 8 is operate, the return ratio of the answer signal which represents the receiving is impossible (busy) is reduced by making stay the order on a bus, and the reduction of the processing capability of the CP can be prevented.

Title: Ventilation fan for use in duct
Inventor: ISHIZU TETSUO
IPC: F24F7/10
Filed: 1987-06-30
Abstract: PURPOSE:To remove a wasteful air flow and reduce a noise by providing a curved-face part having the same configuration as that of an imaginary cut-away part of a blast casing on the upper surface of the main body thereby to form a vent path, and further forming the upper surface corner part of the main body into a curved-face part. CONSTITUTION:A blast casing 4 has an opening 4c the upper part of which is horizontally cut and a part of which is cut away. In a main body 1, a part of the upper surface part 1a is worked into a curved-face part 8 having the same configuration as that of an imaginary cut-away part of a blast casing 4, and the curved-face part 8 which is brought into contact with an opening part 4c forms a vent path 7. Then, air sucked up through a main body suction port 1b smoothly flows without causing a phenomenon of flowing back within the main body 1 because the height of the side surface part 5 of the main body 1 is lower than the total height H of the ventilation fan for the duct, the depth of the main body 1 is shallow and the corner part 6 of the upper surface 1a is formed into a curved-face shape. Thus, sucked air is sucked through a suction port 4a and a noise is reduced.

Inventor: IWASAKI MOTOAKI
IPC: G01N15/00
Filed: 1996-06-24
Abstract: PROBLEM TO BE SOLVED: To efficiently collect particles adhered to a body to be measured by collecting the particles adhered to the body to be measured by a rotating stage and a moving means. SOLUTION: A wafer 1 is put on a rotating stage 2, and suction of particles is started by a suction nozzle 5. The wafer 1 is rotated around a rotating shaft in this state, and moved in X-axial direction by a horizontal driving stage 3. When the circumference of the wafer 1 approaches the nozzle 4, the gap with the wafer 1 is controlled. This gap is kept following the movement, and at a point of time when the rotating shaft is situated in the center of a nozzle A or slightly passed through it, the sampling is terminated. Thus, a filter 6 completely scans the whole surface of the wafer 1, and the particles on the wafer 1 are efficiently sucked by the nozzle 4.

Title: Operating speed selector circuit for hydraulic excavator
Inventor: SANO NOBORU
IPC: F15B11/04
Filed: 1996-06-24
Abstract: PROBLEM TO BE SOLVED: To make possible selecting easily operating speed in accordance with an attachment to be mounted to a hydraulic excavator. SOLUTION: Adjusting the displacements of hydraulic pumps 10, 11 is made possible by providing variable displacement hydraulic pumps 10, 11 and supplying and discharging oil to inclination adjusting cylinders 21, 22 by the operation of an electromagnetic selector valve 23.
